You dont mention if this is for PvP or for PvE or what level you are?
Im only level 41, but recently dropped Archon in favour of 8 points into Chloro for the instant Bloom cast.
The 5% extra damage boost from archon is mitigated by the fact i can heal myself (or others) for 1200 every 10 seconds which at least triples your survival time (so 200-300% more damage). Its also hilarious to hit a player with a chloro spell, them think, HA! this wil be easy, then spank them for 10,000+ points of damage over the next 15 seconds while healing myself.
51 point pyro build with chloro http://rift.zam.com/en/stc.html?t=0z...ueuusuts.Vb.xd
Unless im opening a combat, i never use cinder burst unless it procs off the pyro armour (i dont use the standard damage mitigation armour - chloro takes care of that)
opener : ground of power > burning bonds
standard rotation : countdown > flamebolt > fulminate > FireBall > FireBall > FireBall
if flame bolt procs from fireball : flamebolt > flamebolt > flamebolt (builds charge faster)
if cinderburst procs from armour : fireball > flamebolt > cinderburst (high burst as flamebolt and cinderburst are instants)
throw in ancillary heals and debuffs as required and hit either smoludering power or internalize charge the second it hits100 charge
if im in pvp i change it around a little so i can spike damage after they cast a heal and try to panic them
another option is go 31 points into both pyro and elementalist to get the +50% elem damage and the bigger pets
its by no means perfect or "the best" build, but it works for me.
